Metasoma ( Fig. 56A, D, F–H View Figure 56 ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, virtually parallel-sided over most of length, but narrowing over distal 1/3 and apex truncate (length 0.29, maximum width 0.14, minimum width 0.10), petiole with little pubescence on distal half. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.10, length T2 0.15), edges of median area polished and lateral grooves deep, median area broader than long (length 0.10, maximum width 0.15, minimum width 0.06); T2 with scattered pubescence throughout. T3 longer than T2 (0.20, 0.15) and with scattered pubescence only distally. Pubescence on hypopygium dense.
Cocoons. Beige or gray-white oval cocoons with silk fibers evenly smooth. Cocoons forming two parallel rows of cordwood with the caterpillar in the middle.
The specimens are slim.
( Fig. 57 A–J View Figure 57 ). Similar in shape and coloration to the female.
Christer Hansson is the curator Museum of Zoology, faculty of Science at Lund University, Sweden. He is interested in some Chalcidoidea families.
The parasitized caterpillars were collected in Costa Rica, ACG, Sector El Hacha (Finca Araya and Sendero Tigre), during July 1999 and October-November 2001 at 280 m and 295 m.
The lifestyle of this parasitoid species is gregarious.
